The 30W charger is indeed faster than the 20W one for charging speed, especially suitable for scenarios where quick power replenishment is needed. For example, when charging an iPhone 14 or newer models, the 30W charger can get closer to the device's 25W peak charging power, which has a clear advantage over the 20W charger's actual output of about 19W. If you also own devices like an iPad or MacBook, the 30W charger offers better compatibility, reducing the hassle of carrying multiple chargers. It is smaller in size, lower in price (about 50 to 80 ringgit, while the 30W one is about 100 to 150 ringgit), and has less impact on battery life. If you mainly charge at home or in the office and don't pursue extreme speed, the 20W charger is a cost-effective choice. The difference in charging speed is more obvious when the battery level is below 80%, and the gap will gradually narrow in the later stage due to the battery protection mechanism.
